Shift-Vertical
A Shift-Vertical was a standard Fence obstacle used in swoopchasing. Shift-Vertical fences required the swoopchaser to guide their swoop under the barrier. The counterpart to the Shift-Vertical was the Vertical. The Cantina Hangover, Dianoga Swamp Trap, and Rancor Pit Fences were all Shift-Verticals.[1]
